An NBC suit is the first line of defence in any CBRN preparedness kit, and most of what gets sold as one in 2026 offers zero chemical protection at all — here's what MilitaryMart actually stocks, and what to walk past.
- TrellChem Hazmat Suit Level A (£125) is the only rated nbc suit here — buy it in 2026.
- Skip boiler suits and costume one-pieces sold as nbc suits; they carry zero chemical protection rating.
- Pair any nbc suit with a sealed respirator — the £1.50 Dutch Army mask is for collectors only.
- Surplus NBC suits and masks can be decades old — check gasket condition before trusting the seal in 2026.
Why this matters
CBRN prepping isn't just gas masks and stockpiled tins anymore. Surplus stores across the UK carry old-issue chemical suits, ex-forces respirators and decommissioned NBC kit pulled off government contracts, and in 2026 a lot of it gets listed with no protection rating attached at all.
A genuine nbc suit needs three things working together: a rated barrier suit, a sealed respirator, and gloves and boots that actually interface with the suit cuffs. Buy one piece without the other two and you've got a costume, not protection. The NBC respirators guide covers the mask side of that kit list — read it alongside this one before spending anything.
Who this is for
This guide is for preppers and CBRN-aware households building a go-bag or a home store, not professional HAZMAT responders who need certified, paperwork-backed suits for occupational use. If you're supplementing food, water and first-aid kit already in the house, keep reading. If you need suits rated for chemical handling on the job, buy new from an industrial safety supplier, not surplus.
What to look for in an NBC suit for preppers
Protection level (A through D)
US and NATO systems grade chemical protection from Level A — full encapsulation, self-contained air — down to Level D, basic work coveralls. Most home preppers only need Level B or C protection against airborne or contact exposure, but know exactly what you're buying. A suit with no letter rating printed anywhere is not a graded nbc suit, whatever the listing calls it.
Respirator and mask seal compatibility
The suit hood has to seal against your mask, not just sit near it. A loose hood-to-mask fit is the single biggest failure point in surplus CBRN kit, and it's the reason the respirator matters as much as the suit itself.
Sizing and mobility
A suit two sizes too big bunches at the cuffs and lets air in exactly where the seal needs to be tightest. Try it on over normal clothing before you commit, and check chest and waist sizing against the listing, not the generic size label.
Shelf life and seal integrity on surplus stock
Rubberised seals and gaskets on decommissioned NBC suits degrade with age regardless of how mint the suit looks. A suit stored since the 1990s can look untouched and still have perished elastic at the cuffs and hood.
Decon and glove/boot interface
Suit sleeves and legs need to tape or seal over gloves and boots, not just tuck in. Check for built-in cuff straps or tape points before buying — a suit without them needs separate sealing tape to be usable in a real incident.
Realistic budget against certified gear
A genuinely rated Level A suit costs more than a boiler suit dyed olive green, and that price gap is the protection you're paying for. Budget for the suit and the respirator together, not the suit alone.
Top picks
TrellChem Hazmat Suit – Level A — the only genuine buy
£125 buys a Level A rated suit, the highest protection grade MilitaryMart lists in 2026. This is full encapsulation gear built for chemical handling, not a stencilled boiler suit repurposed for the prepper market. Buy it if you want an actual rated barrier suit, and pair it with a proper respirator rather than a display-only mask.
Dutch Army M89 NBC Mask with Straps New — the collector's piece, not the lifesaver
£1.50 gets a genuine Dutch Army NBC mask, new in its original packaging, and it's listed as sold for display purposes only. This is a militaria item for a collection shelf, not a filter you strap on before an incident. Skip it for actual CBRN use, Consider it if you collect genuine Cold War-era NBC kit.
Dutch Army Tool/NBC Bag – DPM — the kit organiser
£7.50 gets a genuine Dutch Army cordura pouch built to carry tools, NBC equipment or first-aid supplies, and it straps onto webbing or a belt kit. It doesn't protect you from anything itself, but it keeps a suit, gloves and spare seals together and grab-ready. Consider it as the bag that holds the rest of your kit together.
Fjällräven Medical Rucksack — the decon and first-aid carrier
A dedicated medical rucksack gives you a separate carry for burns dressings, wound kit and decon wipes, kept apart from the suit itself so contamination on one doesn't reach the other. Consider it for any CBRN go-bag built around more than just the suit.
Portwest S999 Euro Overall — looks the part, isn't
£26 buys a work boiler suit that gets sold on general marketplaces as "NBC surplus" purely because it's one-piece and olive-toned. It carries no chemical rating of any kind. Skip it for CBRN preparedness — buy it if you just need a workwear overall for the shed.
What to avoid
- Costume and airsoft one-piece suits sold as tactical or NBC gear — no seal, no rating, no protection.
- Unrated "NBC suit" listings on general marketplaces with no Level A/B/C/D grade stated anywhere in the description.
- Ancient rubber-seal kit bought purely for the look — a suit from the 1980s with perished gaskets fails exactly where you need it to hold.

FAQ
What is an NBC suit?
An NBC suit is a protective garment rated against nuclear, biological and chemical contamination, ranging from Level A full encapsulation down to Level D basic coveralls. Most surplus NBC suits sold in 2026 are ex-forces issue rather than new manufacture, so check the protection level stated before buying.
How much does an NBC suit cost in 2026?
A genuine Level A rated NBC suit like the TrellChem Hazmat Suit costs around £125 in 2026. Unrated boiler suits marketed as NBC gear run cheaper, around £20 to £30, but carry no chemical protection rating at all.
Is an NBC suit the same as a hazmat suit?
Yes — NBC suit and hazmat suit describe the same category of nuclear, biological and chemical protective clothing, graded Level A to D by protection standard. The terms are used interchangeably across military surplus and industrial safety listings.
Do surplus NBC suits still work?
A surplus NBC suit can still offer protection if the seals, gaskets and hood are intact, but age degrades rubber components regardless of how the suit looks. Check manufacture dates and inspect cuffs and hood seals before trusting a decades-old suit for CBRN use.
Can you wear an NBC suit without a respirator?
No — an NBC suit without a sealed respirator leaves your airway exposed, which defeats the point of the suit entirely. The suit and mask need to seal together at the hood, not just sit near each other.
What size NBC suit should preppers buy?
Size an NBC suit to fit over normal clothing without bunching at the cuffs, since loose fabric at the wrists and ankles is where seals fail first. Check chest and waist measurements against the listing rather than relying on a generic small, medium or large label.
Where can I buy a genuine NBC suit in the UK?
MilitaryMart stocks genuine ex-forces and rated NBC and hazmat suits alongside NBC masks and storage bags in 2026. Buying from a surplus retailer with grading stated on each listing is safer than an unrated marketplace suit with no protection level given.
Is a boiler suit the same as an NBC suit?
No — a boiler suit is unrated workwear with zero chemical protection, even when it's dyed olive green and sold as surplus. An NBC suit carries a stated protection level, Level A through D; a boiler suit carries none.
One last thing
The £1.50 Dutch Army NBC mask outsells actual protective suits on collector demand alone — proof most people buying NBC kit in 2026 want militaria, not medicine. If you actually need chemical protection, spend the £125 on the TrellChem suit and put the rest of the budget into a rated respirator, not into cheap display pieces that only look right in a photo.
